I'm on rock-band schedule, so I can't guarantee I'll be awake. You can listen to the draft here. It's at 9:00 EST.
...Actually predicting who will get picked in the Rule 5 is always such a crapshoot, since every year there are a number of players who come up in every pre-draft conversation but still don't get drafted. So who knows. But I'd look for the Pirates to take a pitcher, maybe someone who might eventually start but can be hidden in the bullpen for a while.
